Narrative:

Nose gear unsafe on final approach to runway at ZZZ. Went around and recycled gear per procedures to no avail. Accomplished all other procedures in accordance with abnormals and had flight attendants brief for ground evacuate/evacuation. ATC had king air approach for visual check and nose gear appeared down. Landing and rollout on runway 13R was uneventful. Maintenance responded quickly, pinned gear, and prepared for tow-in. I asked for numerous clarifications about strapping the nose gear prior to towing. Answer of all concerned was that it was not required in accordance with all maintenance manuals and procedures. Upon releasing the brakes and beginning tow, the nose gear collapsed. Shut down both engines, elected to keep passenger on board. Finally deplaned through forward passenger door using pickup truck as stairs. Secured aircraft. Callback conversation with reporter revealed the following information: the reporter stated he would not answer any questions relating to this incident. The reporter said that pinning the nose gear on a fokker 100 is no guarantee the gear will not collapse.
